The Australian Dental Association highly recommends dental sealants as an effective method of preventing cavities in the molars. The molars have a rough surface with pits and fissures that are quite a friendly place for cavity-causing bacteria and leftover food to hide. The worst part is, the molars are difficult to clean with your toothbrush, making them very vulnerable to tooth decay.
A dental sealant can be an effective solution, which is a thin, protective coating made of plastic that can be applied on the pits and fissures to keep decay away. Molars develop at the age of six years while the second set breaks through around age 12, both of which are ideal times to get dental sealants. The process is pain-free and is quite effective too, as it prevents up to 80% of the cavities.
